View 3 Replies View RelatedI use the following method for preventing the users from changing their passwords , is there any other method other than this ?
ls -l /usr/bin/passwd
-rwsr-xr-x 1 root root 37140 2010-01-26 12:09 /usr/bin/passwd
so we need to remove the suid for that command as follows :- chmod u-s /usr/bin/passwd now normal users won't be able to change their own passwords - and only the root user will be able to do it for them.

View 5 Replies View RelatedI want the users to access servers via ssh public key only. By default they don't know their initial password and do need to change that when performing administrative tasks.For changing their passwords without knowing the old they need to switch to root for this special case.The only case it seems I don't have control is that users can not only change their password but also the password of other peoples. Does someone sees a solution (without apparmor/selinux and special /usr/bin/passwd.sh) to restrict users to only change their password?I miss the feature of using environment variables in sudoers file.

time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null"
If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password:
open("/dev/urandom", O_RDONLY) = 6
read(6, "36&{35121221234320234313242312I326235245224300354O)270Q200 201J227224311_212367"..., 640) = 640

View 3 Replies View RelatedI know I can ssh login without password from a local to a remote. My question is how I can ssh without password from the remote to another remote. Say, I have three machines: A, B, C where A is the local machine. I use the same private/public key pair for all the login. What I can do are:
1. ssh from A to B.
2. ssh from A to C.
3. If I am sitting in the computer B (or B is local), then I can ssh from B to C.
What I am not able to do is:
After I ssh from A to B, I cannot ssh from the B to C. When I try to ssh from B to C, it asks me a passphrase.
I'm new to SUSE Linux 10 and I am having a problem with a local user account. Here is the scenario,Logged in successfully to a putty session as the "user" and try to change the password :

I am unable to change the password as the user but i am able to log into the server with the same user.
I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious.I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users.Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways?(I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password.

View 3 Replies View RelatedI have setup a nis server and client. At first I didn't have a local user defined on the client. The client then used the user and passwords from NIS, so that was ok.
The problem then is, that when the server is down, I couldn't login to my client anymore. So I created a local user with the same name on the client but with a different password (after I shut the nis server down, if nis server was on, I couldn't create a local user with the same name). I then edited etc/nssswitch.conf as follows:
Code:
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# compat Use compatibility setup
[Code].....
If NIS server is on: client has to login with the nis password If NIS server is down: client has to login with the local password (as fallback)
However the actual behaviour is that I can only login with the local password now. The NIS pasword doesn't seem to be used anymore.
I have no fracking clue what my password is and I want to create multiple user accounts. I have no idea whether or not I need to re-install the OS or what..nor can I even begin to imagine how to do so without a CD drive..I should also note I didn't start her up myself.

A piece of my config:
Code:
I have an RHEL 5.3 system where NIS logins are working perfectly, but authentication doesn't seem to be working for non-root local users. I can't login either remotely or at the console with a local user, and I can't even su to them unless I'm doing so from root (i.e. when no password is required).
I've reset the password, I've deleted and recreated the user, and nothing. nsswitch.conf does have "files" listed as part of the config, which was really the main place I'd have assumed the issue could be. su gives "incorrect password", and ssh gives "userauth failure". /var/log/secure shows "su: pam_listfile(su:auth): Refused user <username> for service su", and same for the ssh attempts (with ssh in for su, of course). I've reviewed my pam.d files, and they seem to be the same as on a working machine, but I'm not 100% conversant with pam so I might be missing something.
How do I stop users from changing their background? I'm installing ubuntu on some (non-networked) computers at my school, and I don't want the students to change the background on the desktop.

View 9 Replies View RelatedI am stuck in a weird situation and could definitely use some help from gurus in security area.
I have categorized my users into 3:
1. root user
2. other local users
3. LDAP users
I want to setup following 2 usecases:
a)
1. Allow keybased ssh and scp to root users
2. Allow ssh but disallow scp service to other local users
3. Disallow ssh and scp to LDAP users
b)
1. Allow keybased ssh and scp to root users
2. Disallow both ssh and scp to other local users
3. Disallow ssh but allow scp to LDAP users
For the 1. in both cases, I think PermitRootLogin in sshd_config could . For the 3. I am thinking of deploying rssh to control scp service access, since ssh will be restricted anyways.
Problem area is 2. primarily.
i) How to allow ssh but disallow scp to 'other local users'
ii) How to disallow both ssh and scp to 'other local users'
